POLICY 10 YEARS: 10.4 MILLION SQUARE FEET TORONTO’S GREEN ROOF BY-LAW A MODEL 1.2 MILLION-SQUARE-FEET AND COUNTING By Steven W. Peck ities around the world have begun mandating green roofs on their new buildings because they turn wasted roof spaces into green infrastructure that generates multiple benefits. Toronto’s leadership with the Green Roof Bylaw is helping law makers across North America. For example, in Devens, Massachusetts, they recently used the Toronto Bylaw to model their new green roof policy which also includes a requirement for accredited Green Roof Professionals (GRPs) to work on green roof project teams. Toronto’s Bylaw has already resulted in more than 1.2-million-squarefeet of new green space planned on new commercial, institutional, and multi-unit residential developments across the City. The Bylaw came into effect January 31, 2010 and the resulting public and private green roof benefits will include the following: • More than 125 full-time jobs related to manufacture, design, installation and maintenance. • Reduction of more than 435,000-cubic-feet (approx. 50 olympicsized swimming pools) of stormwater each year. • Tangible reduction of the urban heat island effect, the artificial overheating of the city. • Annual energy savings of over 1.5 million kWh for building owners and improved air quality.
